Benefits and risks of participating
Tracking your blood pressure and mood data may enable you to be more aware of your blood pressure and mood and can inform your next doctor’s visit, leading to better control of your medical condition. Hence, there may be minimal direct benefit to you from participating in this study.

• The application consumes power, so nightly charging is recommended. With typical phone use, a smartphone running the study application should have enough battery power to last all day.
• The GPS on your smartphone already collects data on where you are at all times. You may experience a sense of loss of privacy as a result of sharing your GPS location. For our study, this data is not transmitted or viewed in real time.
• You may experience discomfort when completing the daily activities or answering survey questions.
• There is the potential for loss of personal data. While we will make every effort to ensure that your data remains confidential, it may be lost due to loss of your device, hardware or software failure, and other reasons. If you feel uncomfortable with any study activity, you may discontinue participation at any time, either temporarily or permanently.
• For more information about risks and side effects, ask one of the researchers.
